Bare Copper Solid & Stranded

Applications X

Solid and stranded (classes AA and A) bare copper are suitable for overhead transmission and distribution applications. Stranded conductor or greater exibility (classes B and C) are suitable for uninsulated hook up, jumpers and grounds in electrical construction. Soft Drawn copper is unilay construction. Standards & References X Bare copper wire and cable meets or exceeds the following ASTM speci cations:

• B-1 Hard-Drawn Copper Wire • B-2 Medium-Hard Copper Wire • B-3 Soft or Annealed Copper Wire • B-8 Concentric-Lay-Stranded Hard, Medium-Hard or Soft Copper Conductor • B-33 Tinned Conductors • B-787 19 Wire Combination Unilay-Stranded Soft Copper Wire Construction X Bare copper, solid or stranded. Available in tempers hard, medium-hard or soft. Stranded conductors are concentrically stranded in hard and medium-hard tempers and are Combination Unilay stranded in the soft-drawn temper.
